About Thinx: Our washable, reusable undies absorb your period and are a more sustainable solution than single-use disposable products. Depending on your flow (light, medium, heavy), Thinx can replace pads, tampons, liners, and cups, or be worn with tampons and cups for extra protection. Like regular underwear, but so much better.
